About half way through https://www.freebsd.org/doc/handbook/firewalls-ipfw.html 
it says:

> # Allow outbound NTP
> $cmd 00260 allow tcp from any to any 37 out via $pif setup keep-state

But that doesn’t allow NTP. NTP uses UDP 123. TCP 37 is the obsolete TIME 
protocol. (Unless I am completely at a loss, of course.)
